Abstract: A system and method are provided for using differentiated telephone numbers to determine whether to perform a vocoder bypass. In an exemplary embodiment, a mobile station may call a terminating node. An intermediate entity may search an identifier of the terminating node for a predetermined aspect. If the predetermined aspect is found, the terminating node may be a mobile station, and the intermediate entity may perform a vocoder bypass. If the predetermined aspect is not found, the terminating node may be a non-mobile station, and the intermediate entity may perform vocoding.
